All-in-one Ice Bath | White

The Khao eliminates the clutter of separate chillers, hoses, and filtration units. Everything sits inside one clean, white unit — chiller, pump, ozone sanitation, and filtration all built into the tub's housing. Plug it in, fill it up, set your temperature via the app, and you're done.

The seamless acrylic interior is non-porous, meaning it does not absorb bacteria and is easy to clean. The insulated shell keeps your water at the target temperature without the chiller running constantly, cutting energy costs and extending equipment life.

For those who want cold therapy without the industrial look of external equipment, the Khao delivers performance in a package that looks like it belongs in a high-end spa.

Installation

• 1. Position the unit on a flat, level surface near a power outlet
• 2. Ensure adequate ventilation around the unit for heat dissipation
• 3. Fill with clean water to the indicated line
• 4. Plug into a grounded 220V outlet

• Note: Unit requires approximately 50cm clearance on all sides for airflow. Indoor installation is recommended for optimal performance and longevity.

Ice Bath Care & Maintenance

• Your Sisu ice bath is built to last with minimal upkeep. A simple routine keeps the water fresh, the equipment running efficiently, and your cold plunge experience at its best. Whether you're using an integrated chiller system or adding ice manually, these steps will help you get the most out of your investment.
• The key to low-maintenance ownership is consistency. A few minutes after each session and a short weekly check prevents the kind of buildup that leads to bigger jobs down the track.

After Every Session

• Shower before entering. Body oils, sunscreen, sweat, and lotions are the number one cause of cloudy water and filter clogging. A quick rinse before you plunge makes a significant difference to water quality.
• Replace the insulated lid immediately. This maintains water temperature, reduces energy consumption on chiller units, and keeps debris, insects, and leaves out of the water.
• Wipe down the rim and any exposed surfaces with a clean cloth to prevent waterline buildup.
• Remove any visible debris from the water with a small skimmer net.

Weekly Routine

• Check water clarity and smell. Clean water should be clear with no odour. If cloudy or smelly, change the water regardless of when you last filled it.
• Clean or rinse the filter element (chiller models). Remove the cartridge and rinse under running water — takes under two minutes and keeps circulation at full flow.
• Wipe the waterline around the interior with a soft cloth or non-abrasive sponge. Mild dish soap or diluted white vinegar is all you need.
• Test water quality if you're using sanitising tablets or water treatment products. Simple test strips from pool supply shops give a quick read on pH and sanitiser levels.

Fortnightly (Chiller Models)

• Check the ozone generator is functioning. Most units have an indicator light — if it's off or flashing, consult your user manual or contact us.
• Inspect hose connections between the chiller and tub for leaks or loosening. Tighten fittings by hand — don't overtighten.
• Clean the chiller's air intake and exhaust vents. Dust and insects accumulate quickly in Thailand's climate. Wipe or vacuum the vents to maintain airflow and cooling efficiency.

Monthly Routine

• Deep clean the interior. Drain completely, wipe all interior surfaces with a mild cleaning solution, and rinse thoroughly before refilling. For stainless steel, use a dedicated stainless steel cleaner. For composite or timber, use only approved products for that material.
• Replace the filter cartridge if showing wear, discolouration, or reduced flow even after rinsing. Most filters last 2–3 months depending on usage.
• Inspect the drain valve and plug for signs of wear or slow leaking. Replace seals if needed.
• Timber exteriors: Check for cracking, splitting, or discolouration. Apply recommended timber treatment oil if the wood appears dry. Thailand's UV and humidity accelerate timber aging.

Water Change Schedule

• With chiller, ozone, and filtration: Change every 2–4 weeks depending on usage. Heavy daily use or multiple users requires more frequent changes.
• Without a chiller (manual ice): Change after every session, or at minimum every 2–3 days. Standing water without sanitation becomes a breeding ground for bacteria in Thailand's warm climate.
• Always use clean tap water. If your supply has high mineral content, consider a basic inline filter on your garden hose to reduce calcium buildup.

Seasonal Tips for Thailand

• Hot season (March–May): Expect longer cooling times and higher energy use. Ensure good ventilation around the chiller and keep it out of direct sunlight.
• Rainy season: Outdoor tubs need more frequent cleaning. Check for debris buildup and ensure the area around the base has adequate drainage.

What to Avoid

• No bleach, pool chlorine, or harsh chemicals. These damage interior surfaces, seals, and chiller components. Use products designed for small cold plunge systems, or ask us for recommendations.
• Never leave the tub uncovered. Uncovered water in Thailand attracts mosquitoes and debris rapidly.
• Don't run the chiller without adequate water level. The pump must be fully submerged. Running dry damages the pump and voids your warranty.
• Don't pressure wash timber exteriors. High pressure forces water into the grain and causes splitting. A gentle hose and wipe is sufficient.

Chiller Maintenance

• Keep the unit on a level, stable surface with at least 30cm clearance on all sides for airflow.
• Visually check refrigerant lines for damage or wear. Do not attempt refrigerant repairs yourself — contact us or a qualified technician.
• The compressor and fan are sealed units requiring no user maintenance. If you hear unusual noises, frequent cycling, or the unit isn't reaching target temperature, contact support.
• Clean the condenser coils every 3–6 months by gently brushing off dust and debris. This is the single most impactful task for chiller longevity and efficiency.

When to Contact Us

• Water not reaching target temperature despite clean filters and vents
• Unusual noises from the chiller or pump
• Error codes on the digital controller
• Ozone generator not activating
• Any leaks from the tub, fittings, or chiller unit
• Visible damage to the interior surface
• Questions about replacement parts or filter cartridges

Warranty Reminder

• Regular maintenance as outlined above is a condition of your warranty. Keep a simple log of water changes and filter replacements — this protects you in the unlikely event of a warranty claim and helps us diagnose issues faster.

**Q: How is this different from a tub with a separate chiller?

A: Everything is integrated — no hoses, no external box, no additional floor space needed. Cleaner look, simpler setup, fewer potential leak points.

**Q: How cold can it get?

A: Down to 3°C. Most users find 5-10°C optimal for cold therapy benefits.

**Q: How long to cool down from room temperature?

A: First fill takes 12-24 hours, depending on ambient temperature. Once cold, the insulation maintains temperature efficiently with minimal chiller cycling.

**Q: Is it noisy?

A: Quieter than most external chillers. The compressor is designed for indoor use with noise-dampening housing. You'll occasionally hear it cycle on, but it won't disrupt the household.

**Q: Can I use it outdoors?

A: Designed primarily for indoor use. Outdoor installation is possible in covered areas, but direct sun exposure reduces efficiency and may affect the acrylic finish over time.

**Q: How do I control the temperature?

A: Two options — the built-in digital panel on the unit, or the smartphone app via WiFi. Set schedules, adjust temperature remotely, and monitor status from anywhere.

**Q: How often should I change the water?

A: With the ozone sanitation running, water stays fresh for 3-4 weeks under normal use. Add a maintenance dose of water treatment monthly for best results.

**Q: What maintenance is required?

A: Wipe down the acrylic interior weekly. Clean or replace the filter monthly. Drain and refill every 3-4 weeks. Run the ozone cycle after each use.

**Q: What's the warranty?

A: 1 year covering manufacturing defects, compressor, and electrical components. Does not cover damage from improper installation, power surges, or cosmetic wear.
